The utilization of unmanned aerial vehicle (UAV) remote sensing allows for fast and effective soil moisture content (SMC) monitoring. Scale conversion can obtain remote sensing images at multiple resolutions and offer the possibility of improving the estimation accuracy of SMC, which is significant for precision agriculture. To explore the effect of upscaling conversion on SMC monitoring with UAV remote sensing, multispectral images and SMC data at different soil depths were acquired.
